The iconic fundraising festival will take place Sept. 22 at Hersheypark Stadium in Hershey, PA, and will also feature Jack Johnson, ALO, Pegi Young & The Survivors and Lukas Nelson & Promise of the Real. Long-time collaborator Tim Reynolds will join Matthews for his sets.

Tickets for the event go on sale July 13 via LiveNation, Ticketmaster and GIANT Center Box Office. More information is available via Farm Aid 2012's website.

The annual benefit will fill the concessions with local and organic foods from family farms and give concertgoers the opportunity to meet the farmers and engage in hands-on activities.

"Our country faces pressing challenges, and none of them will be solved without family farmers," Carolyn Mugar, executive director of Farm Aid, said in a press release. "The Farm Aid concert brings farmers and eaters together to grow the kind of agriculture that builds stronger communities and a healthier food system. This year, we look forward to celebrating the ingenuity of farmers from Pennsylvania and all across the United States."

Farm Aid got its start in 1985 and is the longest-running benefit concert series in America. Over the past 27 years, more than $39 million has been raised to help family farmers across the U.S.
